To aZZ whom. m 2 concern Be it.- known that 1, Elmer B; l-lnsnmmn, a citizen of the United States, residin" at Chicago, n e county ot'Cook andfi to of Illinois," aveinventeo a certain new and useful improvement in Draft-Yokes for Railway-Car Draft-Rigging, of which the following is a tall, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in draft yokes for railway car draft rigging.

The object of my inve tionis to provide a draft'yoke havlng a secure and readily detachable nieansot engaging the same to the draw ba W In the drawin s forinln a aart this 2) specification Figure 1 IS a side elevation of a front end of a draft yoke and the rear end of a draw bar embodying my invention. Fig. Zis a plan View partly in horizontal section on line 2&2 of Fig. 1 Fig. 3 is a vertical longitudinal section on line 33 of Fig. 2. Fig. 4 is a cross section on line 4- of Fig. 1. v V.

In thedrawings 6 represents a draw bar provided with the butt 7, and having a preferably circular vertical opening 8 to receivethe preferably cylindrical key 9.
